Answer 1

<img> Tag is only working with two (Image in Format like .png , .jpg ), (Or .gif file)

So if you need to add video inside your Site.. You must use <video> Tag like the examples below:

Video Example with Controls:

 <video width="400" controls> <source src="https://techcraze.co.in/wp-content/uploads/2021/03/topp.mp4" type="video/mp4"> Your browser does not support HTML video. </video>

Video Example without controls with autoplay feature:

 <video width="400" autoplay> <source src="https://techcraze.co.in/wp-content/uploads/2021/03/topp.mp4" type="video/mp4"> Your browser does not support HTML video. </video>
